I've migrated not too long ago from Win10 to Kubuntu which is very Windows-like, and the adaptation was quite easy.

However, I have to ask: Are you comfortable typing commands on a terminal or editing configuration files? I ask because while it's gotten much easier to use Linux with just a graphical interface you'll still bump into some annoyances here and there where you'll Google how to fix and it will often tell you to 'run command x in the terminal'
